Research on the welding possibilities of dissimilar welded joints between two special alloys

摘要

Continuous development of the technological processes led to the necessity of using industrial equipment/installations made of high temperature resisting materials that provide the ability to work in heavily corrosive environments.The paper analyses two fusion welding options of dissimilar welded joints between two alloys,a cobalt based and a nickel based alloy.Here in are presented the results obtained after welding the two different materials using Tungsten inert gas (TIG) and Electron beam (EBW).Based on the results obtained after micrographic and macrographic examinations,it has been concluded that the two welding processes can be successfully used at dissimilar welded joints between the two types of material.
